DETAILED DESC~IPTION OF A P~EFERRED EMBODIMENT
In Figs. 1-3, the exterior end 10 of a fuel tank filler tube is illustratedO
The exterior end is the inlet receiving end of a vehicle fuel tank adap~ed to receive the fill nozzle 12 of a fuel pump commonly found at the gas station. Specifically, the fill nozzle 12 is engaged by an inlet forming device or member 14 which is closely interfitted in the end portion 10 of the fuel inlet tube. Specifically, the inletting device 14 is defined by a body 16 having an outer cylindrical surface 18 which is adapted to be press fit within the inner diarneter of the end 10. A radially inwardly recessed channel 20 is formed in the filler tube end 10 to limit the distance which the housing 16 can be inserted into the end 10. The end surface 22 of housing 16 is utilized for this insertion process.
In Fig. Ia, the surface 18 of body 16 of device 14 is sealed with respect to the end portion 10 by providing an elastomeric seal member 16' in an annular groove 21 of the body 16. Further, an annularly formed channel 20' is impressed against the member 16' to produce a particularly good leak resistant sealin~ m~a~s.
¦ As best shown in Figs. 1-3, the inside face of the housing 10 ~n~cll)des a j central aperture forming surface 24. Also, upward from the ape~r6 ~ IS a1 in~ ardly protruding boss 26 adapted to support an end 28 of a fuel tank ~1 c~Lit j~ -2-12855~ ~
30 ~or routin fuel to the :lutomatlc shut-o~f p~rt oi the !ill nozzle 12 (note the openin~ between the end 28 of conduit 30 and the boss 26). The tube 3û extends throu~h the fuel tank filler tube and then to the desired ~ill level of the fuel tank.
When the ~uel entering the fuel tank approaches a ~illed condition, fue~ is forced through the tube 30 to the vicinity of the nozzle 12. This causes the automatic cut-off mechanism in the associated fill nozzle of the gas station to shut off fuel flow.
As previously described, it is desired to inhibit the escap~ of fuel vapor when the fuel tank is filled with fuel. The subject inlet forming device or member is adapted to be utilized with a svstem to capture and store the displaced atmosphere or vapor in the fuel tank as the liquid fuel fills the tank. To prevent the escape of vapor past the nozzle 12, an apertured seal member 32 is supported acr~ss the aperture 24 of the housing 16. Specifically, the seal member 32 has an aperture forming surface 34 with a dimension or diameter conforming to the outer surface 12' of the fill nozzle 12. The aperture conforming surface 34 fairly ti~tly grasps the outer surface 12' to prevent fuel vapor leakage there~etween.
As best shown in Figs. 1 and 2, the seal member 32 is secured to the surface 36 of the housing 16 by means of a combination retainer and filter housing member 38. The member 38 is a substantially ring shaped member having an inner opening 40 providing access for the nozzle 12 to the seal aperture 3~. The member 38 has a substantially cylindrical outer surface 42 which is closel~ engaged by a similarly dimensioned cylindrical surface 44 of the housing body 16. The seal 32 is held against the surface 35 of housing 16 at an annular location about the aperture 24 by means of a circular rim portion 46 formed of member 38. The member 38 and, specifically, its outer surface 42 is tightly slideingly engaged into the housing 16 and specifically the cylindrical surface 44 thereof. The member 38 is thus positioned within the housing 16 so that the rim portion 46 is ernbedded in the seal member 32, thus holding the seal member tightly against surface 36 while allowing an inner edge portion 32' of the seal to be free for slight movement relative to the housing 16 so as to accommodate irregularitie~ in the nozzle 12.
The combira~-~n reWner and filter housin~ member 38 also includes a generally cr~scent sl~¦ ~c~ c~sin~ po tic~n 48. The portio- J18 defines a~
interior which is adaptecl ~ e~n:k a~ ~pen c~ll type foamed plastic filter 50. This I
I
1;~85503 open cell material is permeable ~o vap~rs such as air and fuel vapor, as welJ as being slightly compressible. The portion 48 of thc housing and retainer member 38, as well as the filter materiaJ 50, overlies a crescent shaped outer edge portion 52 of the seal member 32. The resilient nature of the filter material S0 t~nds to urge the edge portion 52 o~ seal 32 against the surface 3~ of the housing 16.
In Figs. 3 and 4, details of the f ilter 50 and housing portion 38 are illustrated. Specifically, the surface forming portion 36 of the housing 16 is apertured by a plurality of ports 54 which extend through the hoùsing from the interior of the filler tube 10 to the seal's outer edge portion 52 which i5 adjacent the filter material 50. This arrangement provides the capacity of venting fuel tank pressure through the filter material 50 by means of moving the edge portion 52 of the seal 32 outward against the natural resiliency of the filter material as shown in Fig. 5. As previously indicated, a system is utilized in association with the subject inlet forming device to accommodate and store the displaced air and fuel vapor when the fuel tank is filled. However, the subject device prevents limited venting of the fuel tank in the event that the aforesaid system does not relieve pressure sufficiently in the tank. When the pressure in a tank again falls below the pressure needed to move the edge portion 52 to the position shown in Fig. 5., the resiliency of the filter material 50 will return the edge portion 50 in sealing relation to the surface 36 of the housing 16, thus blocking the ports 54.
The fuel laden air passing through filter material 50 exits the filter material through face 56 thereof. As shown in Figs. 1 and 2, the face 56 is exposed to atmosphere through apertures located between spaced ramp portions with inclined surfaces 58 of the member 38. Likewise, the lower portion of member 38 has a ramp portion with an inclined surface 60. Both inclined surfaces 58 and 60 facilitate the insertion and guiding of the nozzle 12 through the apertured seal member 32.
Although only embodiment of the subject inletting device for fuel tanks has been described in detall, modifications may be made thereto which still fall within the scope of the following claims which define the invention.
